I'm a super confused and curious person! Maybe I'll ask a few questions rather than introduce the latest science non-fiction ;) I've been having a lot of fun with the circle one in another thread.

This is a problem I had really heard about. I posted elsewhere a picture of me visiting a large centrifuge , and the person showing us around told us about some fruit flies going on it for an experiment. People really study this stuff... even at NASA (https://www.nasa.gov/ames/fruit-fly-lab)! Wow!

The problem: The fruit flies are flying around the jar, which is sitting on a high precision scale.



I looked away for a split second and then looked back at the jar again, and I found all of the flies were tired and resting on the side of the jar. Did the numbers on the scale change ( does X.XXXXX...XX fg = Y.YYYYY...YY fg )? Why or why not?

^ Maybe they have too low unrecognized weight!

It's a high precision scale probably at a place like NASA, ESA, or places that set the standards such as NIST, NPL and BIPM. We can even pretend its precision is better than what I described and call it perfect for the sake of this problem. What would we see?

I mean... they really do ask these questions. Do you suppose they just brush the challenge off and move on?

Another fun fact: fg is femtograms, which is a unit of mass at magnitudes of 10^-15 grams


edit:

We can also make another pretend to see if it spices up the question? What if we pretend these flying insects were like 1 kg each instead of the ones we're familiar with in real life ( they come from some mysterious jungle in RuneScape ). Would that change the solution or problem? What would the answer be in regards to the scale (flying versus non-flying)? Faces of RuneScape (Selfies): 23-24-700-66015963

I see we have some scientists here. Bravo :) I love the answer.

I have another one that confuses me, and it can be for a super large body of water like the ocean although I think one those pools would do the trick.

I've got a rock in my boat. I move the rock out of my boat ( totally not aggressive by kicking it ). The rock sinks to the bottom of the water. Relative to my view: Does the water level rise, fall, or stay the same, and why?



Some people might prefer to use height1 (h1) or height2 (2) for clarification. Faces of RuneScape (Selfies): 23-24-700-66015963
